In All FF's you have your Level up system you use to...of course level up your character and have them learn abilities and whatnot. In FFVII it was Materia, In FFVIII it was Junctions, FFX you had your Sphere Grid and in FFXII you had the License System. So, has anyone seen or heard about what it's like in FFXIII? Is it diffulcult to grasp? If you've seen/heard about it, what do you think about it?
